3 IT NEUTRAL POINT CONNECTION : In the event of use on a 3-phase network with a voltage greater than 480V ±10 % with an isolated or high-impedance system (IT), the internal EMC filter capacitors which are connected to ground must be disconnected. Consult Schneider product support who are the only people qualified to perform this operation. When the speed controller is powered up, the power components and some of the control components are connected to the line supply. It is extremely dangerous to touch them. The speed controller cover must be kept closed.. In general, the speed controller power supply must be disconnected before any operation on either the electrical or mechanical parts of the installation or machine. After the ALTIVAR has been switched off and the green LED has gone out, wait for 3 minutes before working on the equipment. This is the time required for the capacitors to discharge. The motor can be stopped during operation by inhibiting start commands or the speed reference while the speed controller remains powered up. If personnel safety requires prevention of sudden restarts, this electronic locking system is not sufficient: fit a cut-off on the power circuit. The speed controller is fitted with safety devices which, in the event of a fault, can shut down the speed controller and consequently the motor. The motor itself may be stopped by a mechanical blockage. Finally, voltage variations, especially line supply failures, can also cause shutdowns. If the cause of the shutdown disappears, there is a risk of restarting which may endanger certain machines or installations, especially those which must conform to safety regulations. In this case the user must take precautions against the possibility of restarts, in particular by using a low speed detector to cut off power to the speed controller if the motor performs an unprogrammed shutdown. The products and equipment described in this document may be changed or modified at any time, either from a technical point of view or in the way they are operated. Their description can in no way be considered contractual. The speed controller must be installed and set up in accordance with both international and national standards. Bringing the device into conformity is the responsibility of the systems integrator who must observe the EMC directive among others within the European Union. The specifications contained in this document must be applied in order to comply with the essential requirements of the EMC directive. The Altivar 58 must be considered as a component: it is neither a machine nor a device ready for use in accordance with European directives (machinery directive and electromagnetic compatibility directive). It is the responsibility of the end user to ensure that the machine meets these standards. 28

5 Preliminary recommendations Delivery Check that the speed controller reference printed on the label is the same as that on the delivery note corresponding to the purchase order. Remove the Altivar 58F from its packaging and check that it has not been damaged in transit. Handling and storage To ensure the speed controller is protected before installation, handle and store the device in its packaging. Handling on installation The Altivar 58F range comprises 6 sizes of device, with various weights and dimensions. Small speed controllers can be removed from their packaging and installed without a handling device. A hoist must be used with large speed controllers; for this reason they are supplied with handling "lugs. The precautions described below must be observed: 45 max 30

(3) These power levels are for a maximum switching frequency of 2 to 4 khz, depending on the rating, and continuous operation. Switching frequencies are detailed in the section on "Technical Specifications". Using the ATV-58F with a higher switching frequency: - For continuous operation derate by one power rating, for example: ATV-58FHU18N4 for 0.37 kw ATV-58FHD12N4 for 5.5 kw. - If no power derating is applied, do not exceed the following operating conditions: Cumulative running time 36 s maximum per 60 s cycle (load factor 60 %). (4) For 60 seconds. (5) These power levels are given for the maximum permissible switching frequency in continuous operation (2 or 4 khz, depending on the rating). 31

Continuous operation For self-cooled motors, cooling is linked to the motor speed. Derating therefore occurs at speeds of less than half the nominal speed. Overspeed operation As the voltage can no longer change with the frequency, there is a reduction in torque. Check with the manufacturer that the motor can operate at overspeed. Note: With a special motor the nominal and maximum frequencies can be adjusted from 40 to 450 Hz using the operator display module or the PC software. 32

14 Mounting in a Wall-fixing or Floor-standing Enclosure Observe the mounting recommendations on the previous page. To ensure proper air circulation in the speed controller: fit ventilation grilles ensure that ventilation is adequate: if not install forced ventilation with a filter use special IP 54 filters Dust and damp proof metal enclosure (degree of protection IP 54) The speed controller must be mounted in a dust and damp proof casing in certain environmental conditions: dust, corrosive gases, high humidity with risk of condensation and dripping water, splashing liquid, etc. To avoid hot spots in the speed controller, add a fan to circulate the air inside the enclosure, reference VW3A5882i (see catalogue). This enables the speed controller to be used in an enclosure where the maximum internal temperature can reach 60 C. Calculating the size of the enclosure Maximum thermal resistance Rth ( C/W) : θ θ e q = maximum temperature inside enclosure in C, Rth = θ e = maximum external temperature in C, P P = total power dissipated in the enclosure in W. Power dissipated by speed controller: see section Selecting a Speed Controller. Add the power dissipated by the other equipment components. Useful heat dissipation surface of casing S (m 2 ) : (sides + top + front panel if wall-mounted) S K = Rth K = thermal resistance per m2 of casing. For metal casing: K = 0.12 with internal fan, K = 0.15 without fan. Note: Do not use insulated enclosures as they have a poor level of conductivity. Above rating ATV-58FHD28N4, IP54 kits can be used to dissipate power to the outside by ventilation (see catalogue). 39

16 Electromagnetic Compatibility - Wiring Principle Grounds between speed controller, motor and cable shielding must have "high frequency" equipotentiality. Use shielded cables with shielding connected to the ground at 360 at both ends of the motor cable, braking resistor (if fitted) and control-command cables. Conduit or metal ducting can be used for part of the shielding length provided that there is no break in continuity. Ensure maximum separation between the power supply cable (line supply) and the motor cable. Installation diagram 1 Metal sheet machine grounding supplied with the speed controller, to be mounted as shown in the drawing. 2 Altivar 58F 3 Non-shielded power supply wires or cable. 4 Non-shielded wires for fault relay contacts. 5 Fix and ground the shielding of cables 6, 7, 8 and 2 9 as close as possible to the speed controller: - strip the shielding - use the correct size clamps on the stripped part of the shielding to fix to metal sheet 1. 4 The shielding must be clamped tightly enough 7 to the metal sheet to ensure good contact clamp types: stainless steel Shielded cable for motor connection with shielding connected to ground at both ends. 8 6 The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. 7 Shielded cable for connecting the encoder. The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal boxes. 8 Shielded cable for connecting braking resistor (if fitted). The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal cases. 9 Shielded cable for connecting the control/command wiring. For applications requiring several conductors, use small cross-sections (0.5 mm2). The shielding must be connected to ground at both ends. The shielding must be continuous and intermediate terminals must be in EMC shielded metal cases. Note: If using an additional input filter, it should be mounted behind the speed controller and connected directly to the line supply via an unshielded cable. Link 3 on the speed controller is via the filter output cable. The HF equipotential ground connection between the speed controller, motor and cable shielding does not remove the need to connect the PE protective conductors (green-yellow) to the appropriate terminals on each unit. 41

Calculated max. number of pulses per rev. = / 30 = Encoder selection: 5000 pulses per rev., max. standard resolution within calculated limit of 6666 pulses per rev. and programming limit of 5000 pulses per rev. Wiring the encoder Use a shielded cable comprising 3 twisted pairs with a pitch of between 25 and 50 mm. Connect the shielding to ground at both ends. The minimum cross-section of the conductors must comply with the table below to limit line voltage drop: Max. cable length Max. consumption current of encoder Minimum cross-section of conductors 10 m 100 ma 0.2 mm 2 or AWG ma 0.2 mm 2 or AWG m 100 ma 0.5 mm 2 or AWG ma 0.75 mm 2 or AWG m 100 ma 0.75 mm 2 or AWG ma 1.5 mm 2 or AWG 16 Matching encoder outputs There is no need to load with matching impedances. Where several loads (speed controllers, axis control modules, etc) are connected in parallel to the encoder outputs, the resulting impedance must not be below 100 ohms.

26 Wiring Recommendations, Use Wiring recommendations Power Observe the cable cross-sectional areas recommended in the standards. The speed controller must be earthed to conform with the regulations concerning high leakage currents (over 3.5 ma). Do not use a residual current device for upstream protection on account of the DC elements which may be generated by leakage currents. If the installation involves several speed controllers on the same line, each speed controller must be earthed separately. If necessary, fit a line choke for speed controllers ATV- 58FHU18N4 to D23N4 (consult the catalogue). Keep the power cables separate from circuits in the installation with low-level signals (detectors, PLCs, measuring apparatus, video, telephone). Control Keep the control circuits and the power cables apart. For control and speed reference circuits, we recommend using shielded twisted cables with a pitch of between 25 and 50 mm connecting the shielding to each end. Recommendations for use In power control mode using a line contactor : - Do not switch contactor KM1 frequently (otherwise premature aging of the filtering capacitors will occur), and use inputs LI1 to LI4 to control the speed controller, - If the cycles are < 60 s, these measures are absolutely necessary. If safety standards necessitate isolation of the motor, fit a contactor on the speed controller output and use the "downstream contactor control" function (consult the programming manual). Fault relay, unlocking The fault relay is energized when the speed controller is powered up and is not faulty. It has one C/O contact at the common point. The speed controller is unlocked after a fault by: powering down the speed controller until both the display and indicator lamps go out, then powering up again automatically or remotely via logic input: consult the programming manual. Programmable I/O, functions: Consult the programming manual. 51

27 Setup The Altivar is factory preset for the most common operating conditions. Prior to powering up the Altivar: 1 Unlock and open the cover 1 of the Altivar to access the 50/60 Hz selector switch 2 on the control board. If an option card is present, the selector switch can still be accessed. Position the selector switch on 50 or 60 Hz, whichever corresponds to your motor. Preset operating point: 2 or 50 Hz 60 Hz FWD REV ESC ENT STOP RUN RESET 50 Hz position (factory set-up): V 50 Hz 60 Hz position: V 60 Hz Several tools are available to help with setup: - display module ref. : VW3 A58101 (the speed controller is supplied with this display module). - PC software and interface ref. : VW3-A8104 and VW3-A8106 to be ordered separately. If the Altivar is equipped with an I/O extension or communication card, consult the documentation supplied with the card. Reminder for IT neutral point connection: in the event of use on a 3-phase network with a voltage greater than 480V ±10% with an isolated or high-impedance neutral system (IT), the internal EMC filter capacitors which are connected to ground must be disconnected. Consult Schneider product support who are the only people qualified to perform this operation. Checking the thermal state of the speed controller Proceed as follows: - operate the speed controller at the maximum operating and temperature conditions for the application. - Using the display module or PC software, observe until the following parameter stabilizes: DriveThermal.tHd (menu 1-SUPERVISION) It must not exceed 100 %. If this value is exceeded, check the mounting, conditions of use and size of the speed controller. 52

28 Operation - Maintenance - Spares and Repairs Operation Signalling on the front panel of the Altivar POWER z Green LED POWER z FAULT Red LED FAULT on: Altivar powered up on: Altivar faulty flashing: Altivar locked following use of the "STOP" button on the display module or a configuration change. The motor must not be powered up until the "forward", "reverse" and "shutdown via injection" commands have been reset. Display mode on display module screen Displays preset frequency set point or faults. The display mode can be modified via the display module: consult the programming manual. Maintenance Before working with the equipment, switch off the power supply, check that the green LED is off, and wait for the capacitors to discharge (approximately 3 minutes). The DC voltage at the + and - terminals or PA and PB terminals may reach 850 V depending on the line supply voltage. If problems arise during setup or operation, first ensure that the recommendations relating to environment, mounting and connections have been observed. Maintenance The Altivar 58F does not require preventative maintenance.

Assistance with maintenance The first fault detected is memorized and displayed on the display module screen if power is maintained: the speed controller locks, the red LED lights up, and the R1 fault relay is switched off. Consult the programming manual. Spares and repairs For spare parts and repairs to Altivar 58 speed controllers, consult Schneider group product support. 53
